SHEET-METAL FILING.

To all whom 'it may concern:

Be it known that l, NORMAN E. MARSH, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Sheet-Metal Piling.

rlhe object of my invention is to provide a sheet metal piling of simple, durable and inexpensive construction, that may be driven one section at a time, and that may also be removed in the same way for subsequent use.

More specifically it is my object to provide a piling of this kind in which some of the sections are provided with packing strips so arranged that they will permit the joint members to slightly yield to avoid binding when being driven, and to form tight joints after being driven, and further to provide joints between the piling sections so arranged that they may be adjusted to thereby spread and permit the ready and easy withdrawal of one piling section relative to the other.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing" in which- Figure 1 shows a horizontal sectional view through a number of piling sections embodying my invention. Fig. 2 shows a similar view of a modified form, and-Fig. 3 shows a front or outer face view of a completed piling formed of sections, and embodying my invention.

Referring to the accompanying drawings, l have used the reference numeral 10 to indicate a channel bar comprising one of the sections of the piling'. The sections that are to be used alternately with thechannel bars 10 are each formed of a flat metal plate 11 having at one end an angle bar 12, placed with one side flat against the outer face of the plate 11, and the other side at right angles to the plate 11, and spaced apart from the edge thereof far enough to admit one of the edges of the channel bars between them, as shown in F ig. 1. On the inner face of the part of the angle bar 12 that rests against the plate 11, I have placed a sheet 13 of packing material such for instance as heavy felt. On the opposite face of the plate 11, that is to say, the inner surface Specification of Letters Patent.

Application filed March 13, 1908.

Patented June 1, 1909.

Serial No. 420,942.

thereof, I have placed a Z bar 111 with one of its faces against the inner face of the plate 11, another of its faces at right angles thereto, and its third face extending outwardly from the plate 11, parallel therewith, thus forming a chamber between the parts of the angle bar 12 and the Z bar 111, of a size to admit between them one of the flanges of the channel bar 10. The part of the Z bar 14 that is farthest from the plate 11 is arranged to lie flat against the inner face of the channel bar 10. l provide for connecting the angle bar 13 and the Z bar 14 with the plate 11 by means of bolts 15, which are passed through said parts, and provided with nuts 1G on their inner ends, that is to say, the ends that stand on the inner face of the sheeting.

By means of the arrangement described, it is obvious that one section may first be driven to position, as for instance, the channel bar, and then the other section com prising a plate 11 may be placed above the channel bar with the adjacent flange of the channel bar introduced between the angle bar and the Z bar 14. The packing 13 will permit the angle bar to yield slightly relative to the plate 11, so that in the event that there should be a tendency for the channel bar l() to bind between the angle bar 12 and s the Z bar 14, the said angle bar 12 will yield sniiiciently to prevent this binding to such an extent at least, as to permit the plate 11 to be driven. Furthermore, the packing 13 serves another function, which is as follows: L

The adjacent edge of the channel bar 10 will engage the part of said packing that projects beyond the plate 11, and hence will. form a tight joint at this place that will prevent leakage. ln each of the piling members, l have formed an opening 17 in which a hook or the like may be inserted for pulling the piling up.

ln some instances, especially where the piling members have been slightly bent when being driven, it is very diflicult to remove one piling member from the other, and by means of the adjustable fastening of the angle bars 12 and the Z bars 14 with the pil- Y ing plates 11, it is possible for the operator to loosen the nuts 1G and thus permit the angle bars 12 to swing outwardly to such an extent that the piling members may be read ily and easily withdrawn from each other.

If the piling is to be extended around a llO Cil

corner, I place on one of the plates 11 an angle bar 18, and hold it thereon by rivets 19, and I also place against the plate 11 and the angle bar 18 a channel bar 10, all of which part-s are firmly riveted together as shown to the right in Fig. 1.

In the form shown in Fig. 2, I have illustrated a modified form of my invention in which both the piling members are made of sheet metal plates. The only difference between this form of the invention and the form shown in Fig. 1 consists in eliminating` the channel bars 10 and substituting for them plates 20 having riveted to each edge an angle bar 21, the rivets being passed through the angle bars 21, and the Z bar 14T being shaped to clear said rivets. Said rivets are indicated by the reference numeral 22. The piling thus constructed has all of the advantages before described in connection with my preferred form, and simply provides for substituting plates for the channel bars. In this modified form, I have also shown a means for extending piling at right angles, which means comprises two angle bars Q3, riveted to one of the plates 11, and containing between them a plate 20. By the use of these plates as piling members, I am enabled in some instances to use plates of considerable width, thus making fewer members to drive and handle. In some instances, where there is danger of these plates buckling or bending, I reinforce them at their central portions by means of Z bars 24 riveted to the inner faces thereof, as shown 'to the left in Fig. 2.

In practical use, and assuming that the piling members are prepared as before described, I first drive one of the members in any of the ordinary ways, and then place the other member in a coinciding' position, and drive it. I he packing strips will permit su'l'licicnt flexion of the parts to prevent binding and yet when the parts are both driven, the packing forms` a tight oint between the parts, and obviously, after the piling has been used and it is desired to remove same, it may be withdrawn in the ordinary way by attaching a derrick or lifting ack to the top of the piling. However, in case some of the sections should stick, then the nuts 1G may be loosened sufficiently to allow the angle bar 12 to swing out, and permit the withdrawal of the member.

In the following claims, when I employ the term channel bar to designate one4 of the piling members, I refer to a channel bar made either in the way shown in Fig. l, or the modified form shown in Fig. 2, in which the channel bar is made of a plate with two angle bars on its edges.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, therefor, is-

1. In a device of the class described, the

combination with a channel bar and a flat plate, of an angle bar and a Z-bar placed on opposite sides of the fiat met-al plate adjacent to one edge thereof and designed to admit one flange of the channel bar between them, and means such as bolts for adj ustably and detachably securing the angle bar and the Z-bar to the flat metal plate.

2. In a device of the class described, the combination with a channel bar and a flat plate, of an angle bar and a Z-bar placed on opposite sides of the flat metal plate adjacent to one edge thereof and designed to admit one flange of the channel bar between them, and means such as bolts for adjustably and detachably securing the angle bar and the Z-bar to the flat metal plate, said bolts being so arranged that the ends thereof to which the nuts are attached are adjacent to the Z-bar.

3. In a device of the class described, the' combination of a channel bar, a metal plate, an angle bar fixed to one face of the metal plate adjacent to one edge thereof, a packing strip inserted between the angle bar and met-al plate, a Z bar fixed to the opposite side of the metal plate adjacent to the same edge as the angle bar and spaced apart from the angle bar, bolts for securing the angle bar and the Z bar to the plate, said bolts having nuts on the inner ends thereof for adjustably and dctachably connecting the bars with the plate.
